Try this:

That should do it. For now, I've avoided the callback validation rule.

According to the documentation your callback should not start with the underscore
see callback

This rule applies to router, and not the PHP itself, therefore it shouldn't cause a problem, and it really doesn't. Also, I can't find mention of what you say on the given link.

$this->fv->set_message(__METHOD__, 'Incorrect {$field}');

change __METHOD__ to _verifyPassword.
make a var_dump to __METHOD__
edit:

http://php.net/manual/en/language.consta....php#57033

Yeah, I should have used __FUNCTION__ instead. I can't dump that constant, the method never gets called.

@RBX

If you look at the rule and the actual method in the link I am referring as well as into the Form_validation library.

You will see that if you have a callback rule like this:

PHP Code:

$this->form_validation->set_rules('username', 'Username', 'callback_username_check'); 


Your method has to be :

PHP Code:

public function username_check($str)
     {
                ......
     } 


This is because the Form_validation library removes the first 9 characters from the callback method name in the rule,  so it includes the underscore. So if you want your method name to start with an underscore you need to double it in the rule:

PHP Code:

$this->form_validation->set_rules('username', 'Username', 'callback__username_check');

.....


public function _username_check($str)

        {
..... 


Yes, and as can be seen, I'm already using double underscores. It's intentional as validation callbacks need to be public, but I don't want them to be accessible by URL.
